Hi there!

Since you are taking this as an hobbyist, I will recommend you to stay with DX first. Personally, I don't really think you need that jump yet. As you mentioned VLOG, D5200 is more capable and has a bigger advantage here with the flip screen as you can see yourself as you do the VLOG. No one can do VLOG well without looking at the screen and D5200 can perform well here. Besides, assuming you do landscape and portraits often here, you must already have some DX lenses lying around.

So, here is my amateur advice, stay with DX first, get a speedlight (a must for wedding). Train yourself with DX + speedlight well. Then when you are financially capable (capable of buying FF with your photography earnings), then you jump FF for better dynamic range and FF crop sensor. Everything is expensive in FF. DX is cheap and lighter too. I understand this well because I own both D5300 and D750.

There is definitely a huge difference in the focusing speed and dynamic range. Since you are not shooting sports, you don't really have to bother about focusing speed right?

Bokeh wise, it is the lens that matters. Get a 85mm F1.8 for the bokehlicioussss

I bought D750 to shoot for wedding/events. Both is capable of shooting video at 1080p with 60fps and capable of shooting photos at 24MP. But sometimes i prefer to use D5300 since it is so much lighter and it is really tiring to hold a FF camera for video.

I still use D5300 a lot (it is so much lighter and smaller) for casual portraits and landscape.

But when it comes to professional service, people tend to judge a lot. A professional holding a D5300 doesn't look more professional than a noob holding D750.

This is also another reason why I only use D750 during actual day wedding and also corporate event shoots.

That's why I recommend you to go for full frame when you are shooting wedding often. Otherwise, D5300 should suffice.

Actually I once consider D800. 32MP, 1/8000 SS. Super impressive.

But too bad, it shoots max at 1080p with 50 fps. And more expensive than D750

So i got D750 in the end

Yeah true. Sometimes we can also borrow lens from our friends if there is really a need to do so.

Now can afford liao mah

After your japan trip, i am waiting to see you in action with your 70-200!

Do you know that AF speed is slow in kitlens?

Invest in a 50mm F1.8. It can be used in both FF and DX. Then you will have more bokeh already!

Get a 50mm F1.8G. You will notice the difference in bokeh a lot

Although it will be sharper and AF faster than your current kitlens, the sharpness still can't fight good glass la.

Invest on a better standard DX lens. Usually people will buy stock DSLR with kitlens. Then, invest in better standard/prime lenses. If there is really a need, then change a new body and new lenses.

If you have the money wanna straight buy new body and lenses also okay.

Well to be honest, I don't shoot with Sony and so I can't comment much.

I have to leave this question to other sifus to answer.

You have to remember that you need more spare batteries if you are shooting with Sony mirrorless.

Personally, I would prefer to do COD to buy used units. To check not only the condition but also to make sure the seller is legit. Less risk.

Wah so cheap? Second hand SB700 already around rm650

I find slow AF annoying whenever I wanna take candid shots.

The moment you able to focus the subject, the special moment gone

I got that a lot during my days in uni where they asked me to shoot for stage event in college. Some events like orchestra cannot use flash and need to perform under low light. Hard to get good photo.

Wahhh seriously your colleague memang despo. Untunglah!

Wahhh! Nice one man!
